Firs of all: I am still new to MODx and Ditto, so please excuse me if i’m a pain and of course for my english.
And now welcome to another "ever wanted feature for Ditto"
I tried hard to make Ditto 1.0.2 show the tags of a speciefied document ans make them links. But it seems there was no way doing this. So I took a look and found the nice Snippet
TvTagCloud. But It could only archive all tags for a specified folder not only one document. So I wrote a Snippet my self. It’s very basic, thas why I’m posting it here. Maybe you like to extend it. You’re welcome to.
What you need to do is:
- Have a TemplateVariable(TV) which holds tags. Each tag is seperated by a delimiter (e.g. "," which is default)
- Have a Ditto landing page (the one that lists the news)
- Have a Ditto template(Chunk) where you can integrate the Snippet. By the way, you can integrate it where you want to. My DittoTemplate looks like this:
<div class="ditto_summaryPost">
<h3><a href="[~[+id+]~]">[+title+]</a> von <strong>[+author+]</strong> am [+date+]</h3>
<div>[+summary+]</div>
<p>[+link+]</p>
<div>Tags: [[DocumentTVTags? &docid=`[+id+]` &TVtagsName=`tags` &sendTo=`49`]]</div>
</div>
Enjoy!
